Biochemical filtration system (fish tank)

Oh~~~First of all, let me explain that I am not copying.

Except for nitrifying bacteria, those three bacteria you mentioned are the legendary three bacteria. They have always been very controversial. Most of them were proposed by colorful enthusiasts. If you raise some other Fish, it is recommended not to do this, it is not necessary.

First of all, you have fallen into a misunderstanding, that is, you pay too much attention to biochemical filtration. No matter how many bacteria or filter materials with strong surface area, they are all auxiliary. Remember, biochemical filtration is only an auxiliary. The method is based on good physical filtration.

Second, regarding the process of bacterial establishment, what is in your tank when you open it? If there is only an empty tank, it is useless. Bacteria cannot reproduce well without "food". It is recommended to put a small amount of dead grass shrimp, etc. In addition, the yeast must be activated, that is, put it in the container and put Water, etc. (I forgot the details), only when it starts to foam, the specific method is available online, so I won’t copy it~~~~

Third, regarding your filtering, Jiabao~~~~~~ The response is not very good, it consumes electricity, has less water flow, and has a short lifespan. I recommend Ehem's 600 and make a front-end for your barrel. If you have limited money, I recommend the supreme df1300. Your tank is 80cm tall and is the same as mine. I use an EHEIM 600 plus an EF2 as the front. I only put a small amount of glass under the bucket to disperse the water flow, and the remaining space is filled with black water. Cotton (coarse cotton, biochemical cotton), white cotton (filter cotton, fine filter cotton, JBL wool is recommended, very fine, can be used repeatedly for cleaning, which actually saves money in the long run) in the last layer of the water flow. The 600, which has a super strong water flow, has been added with a front. The water is a little weaker, so fish can adapt, but it is still strong, so that the BB can blow up and suck it in. Just wash the ef2 when cleaning. It is very convenient because it uses layers of physical filtration (in fact, the biochemical filtration of black cotton and white cotton is also very strong. Don’t believe what the merchants say about how many times the surface area is). The water is very clear and cannot be seen. The so-called white mist is rarely even small. In this way, there are not many corrupt substances in the water. General biochemical filtration and even nitrifying bacteria on the tank walls and ground sand can be solved. Otherwise, if you focus too much on biochemical filtration, your tank will not be very clear. These are all lessons.

The fourth is your filter equipment. Because the outer filter cartridge is a closed circulation process, the amount of oxygen inside it is very small, so the growth of nitrifying bacteria will be limited, so you'd better Add a water fairy or an internal filter, the kind that can connect to the air outside. In fact, for fish farming, the best is the upper filter and the lower filter, because their filter materials can fully contact with oxygen, and in terms of cleaning, fish have a lot of BBs of. So try to raise as few large fish as possible or reduce the amount of fish

Fifth, let’s talk about the bacteria you are concerned about. Add 2 of trapped water to oxygenate it, add about 5 dead grass shrimps, and add 3 To eliminate nitrifying bacteria, open the filter barrel and release the fish into the tank in 3-5 days. After a week, if the fish in the tank are in good condition, add your fish and other bacteria. You can add a small amount at this time~~~
